Abstract
(DE)
Es wird ein Verfahren und eine Vorrichtung zur Ansteuerung eines elektromagnetischen Verbrauchers (100), insbesondere eines Magnetventils zur Beeinflussung der Kraftstoffzumessung bei einer Dieselbrennkraftmaschine, beschrieben. Der Verbraucher (100) ist in Reihe mit einem Stromsteuermittel (110) geschaltet, das mit einem Ansteuersignal beaufschlagbar ist. Das Ansteuersignal ist von einem Regelmittel (150) vorgebbar. Zur Ermittlung des Schaltzeitpunktes des elektromagnetischen Verbrauchers ist ein Ausgangssignal des Regelmittels (150) auswertbar.
(EN)
The description relates to a process and device for driving an electromagnetic consumer (100), especially a magnetic valve for controlling fuel metering in a diesel engine. The consumer (100) is connected in series with a current controller (110) to which a driving signal can be applied. The driving signal can be predetermined by a control device (150). An output signal from the control device (150) can be evaluated to find the switching time of the electromagnetic consumer.
(FR)
L'invention concerne un procédé et un dispositif permettant d'exciter un consommateur (100) électromagnétique, notamment une électrovanne pour influer sur le dosage en carburant d'un moteur Diesel. Le consommateur (100) est monté en série avec un élément de commande du courant (110) auquel on peut appliquer un signal d'excitation pouvant être prédéterminé par un élément de régulation (150). Un signal de sortie de l'élément de régulation (150) peut être évalué pour déterminer l'instant de commutation du consommateur électromagnétique.
